This attractive, non-yellow Caloplaca usually grows low to the ground. It is found on siliceous rocks, especially the kerbing around graves, but it can also grow on damp limestone, for example, tomb tops, and on basic bark. The granular (isidiate), cracked, blue-grey thallus may be covered with discs (to 1mm diam.), yellow-orange, with a persistent, thick wavy margin the colour of the thallus. Spot tests: disc K+ violet-red. Northern half of Ireland.

Key characteristics

  • Non-yellow Caloplaca, blue-grey, dense with granular isidia, discs yellow-orange
  • Low, acid-rock kerbing in old churchyards and damp limestone tomb tops; disc K+ red.
